The object of my inventio an electric boiler which will any of the above or similar o e ectrical practical manner and for a cousitl ii any sui r What I believe to be novel anti have h ooe x t attention is directed to the accon l 'uicl in the boiler cc description ancl the claims appe i ctrotles to vary the den According to my invention cey are submerged in too wa er: boiler containin the electrooes ano use is.-

gen in boiler flows it a liquid suited to the voltage available through. V v

' K and. heats the liquid, therein he and it then utilize the Vapor thus vaporizing it. The vapors are then carried oil through pipe 9 to the point Where .they are to be used. The vapors from boiler in passing through heating coil 10 are condensed and returned to boiler 5. There is thus established in connection with boiler 5 a closed heating system. This makes it a very simple matter to regulate boiler 5 because the same liquidis boiled continuously and its makeup or electrical resistance does not change. i

The boilers may be run at various temperatures and pressures to meet the requirements of particular cases. Usually it will be desirable to run boiler 5 at a substantially higher pressure and temperature than boiler 7, so there will be rapid interchange of heat between the two and the size of the coil 10 kept Within oractical limits.

Some specinc examples of applications of my invention as follows:

A condition be met wh re low voltage current is available use in opera boiler and the liquid to he vap rized, for example, is quite pure so t -tiii lb has a higi r "istance', in s" h a the boiler may as supplied .W a Water so tion of calcium chloride so or similar substa ce which h tion having relatively low electrical resistance. The liquid oi high res'stance to he ooilet ple Water,

to boiler 'i and is vaporized from boiler 5 coil or pipe Again a con on may he met with T high voltage cu r nt is and th 5 uid to he vaporized has a relatively low resistance for example impure Water. in this case a liquid having high electrical resista-nce, for example pure Water be used the boiler 5 and a liquid having low resistance, for example impure vaporized boiler 7.

in other applications of my invention, it will. be clear "with eithe high resist ance liquid or low resistance liquid used in the boiler 5, any desired liqrxl may be vaporized in the'boiler 'Z'.

it me boiler 5 utilize the ors thererrom to stance of lower boiling point i furthermore, use a substance 1 ch has a hii h boiling noint and -With the apparatus which I now consider to represent the best embodiment thereof, but I desire to have itunderstood that the apparatus shown is only illustrativeand that the invention may be carried out by other means. 4
